BACKGROUND

The present disclosure relates to child restraints, and in particular to juvenile seats for use on passenger seats in vehicles. More particularly, the present disclosure relates to a cupholder included in a juvenile seat.

SUMMARY

According to the present disclosure, a child restraint includes a juvenile seat having a seat bottom and a seat back extending upwardly from the seat bottom. In illustrative embodiments, the child restraint also includes a child-restraint harness coupled to the juvenile seat.

In illustrative embodiments, the juvenile seat includes a cupholder support coupled to the seat bottom and a cupholder mounted on the cupholder support. The cupholder includes a cup receiver having a floor and a side wall arranged to cooperate with the floor to form a cup-receiving cavity sized to receive a drink cup used by a child seated in the juvenile seat.

In illustrative embodiments, the side wall of the cup receiver includes a deformable portion that is unsupported by the cupholder support and is configured to provide crumple means in the side wall for deforming elastically to change from an initial shape and move relative to the floor to assume a different temporary shape and reduce a volume of the cup-receiving cavity temporarily only during exposure of the deformable portion to an external impact force and for returning to the initial shape following cessation of the external impact force. In illustrative embodiments, the side wall of the cup receiver is made of a deformable elastic material to provide the deformable portion of the cup receiver with a deformable elastic quality.

In illustrative embodiments, the cupholder also includes cup-receiver lock means coupled to the floor of the cup receiver for retaining the cup receiver in a fixed position on the cupholder support to locate the deformable portion of the side wall of the cup receiver in spaced-apart relation to the cupholder support. The deformable portion is therefore free to move relative to the cupholder support and the seat bottom during exposure to the external impact force.

In a first illustrative embodiment, the cup-receiver lock means of the cupholder includes a downwardly extending twist lock. The twist lock is coupled to the floor of the cup receiver and arranged to mate with a cup-receiver platform included in the cupholder support following downward movement of the twist lock through an upwardly opening lock-receiver aperture formed in the cup-receiver platform and subsequent rotation of the cup receiver and twist lock about a vertical axis of rotation to cause the twist lock to move on an inclined ramp included in the cup-receiver platform and located under the cup-receiver platform and engage an anti-rotation stop also included in the cupholder support and located under the cap-receiver platform.

In a second illustrative embodiment, the cup-receiver lock means of the cupholder further includes a downwardly extending push-and-snap lock. The push-and-snap lock is coupled to the floor of the cup receiver and arranged to mate with the cup-receiver platform included in the cupholder support after downward movement of the push-and-snap lock through the upwardly opening lock-receiver aperture formed in the cup-receiver platform.

In illustrative embodiments, the seat bottom of the juvenile seat includes a seat pad for supporting a child seated in the child restraint and first and second side bolsters arranged to lie in laterally spaced-apart relation to one another to locate the seat pad therebetween. In illustrative embodiments, each side bolster is arranged to extend upwardly above the seat pad to provide an armrest for a child seated on the seat pad. In illustrative embodiments, each side bolster is a shell formed to include an inner perimeter edge bordering an upwardly opening aperture and the companion cupholder support is coupled to the inner perimeter edge of the shell to lie in a hollow region located under and bounded by the shell and cause the floor of the cup receiver to lie in that hollow region when the cupholder is mounted on the cupholder support.

In illustrative embodiments, the cupholder support includes a cup-receiver platform having a top wall formed to include the lock-passage aperture and a fence coupled to an outer perimeter edge of the top wall and arranged to extend upwardly from the top wall to mate with the inner perimeter edge of a companion shell to hold the top wall in horizontally extending stationary position relative to the companion shell. The cupholder support also includes a downwardly sloping inclined ramp coupled to the underside of the top wall and arranged to extend partly around the lock-passage aperture and an anti-rotation stop located under the top wall at a lowest end of the inclined ramp.

In use, in illustrative embodiments of the present disclosure, a caregiver mounts a cupholder on a cupholder support by holding the cup receiver above the horizontally extending top wall of the cup-receiver platform and then moving the cup receiver downwardly to pass the cup-receiver lock means downwardly through the lock-passage aperture formed in the top wall of the cup-receiver platform. When the cup-receiver lock means of the cupholder is a twist lock in accordance with the first embodiment of the present disclosure, the caregiver then rotates the cupholder about a vertical rotation axis to cause an anchor tab included in the twist lock to move on the downwardly sloping inclined ramp until the anchor tab engages an adjacent anti-rotation stop to block further rotation of the cupholder about the vertical rotation axis so that the cupholder is retained in a stationary position on the cupholder support that is mounted on a side bolster of the seat bottom. In contrast, when the cup-receiver lock means of the cupholder is a push-and-snap lock in accordance with a second embodiment of the present disclosure, the caregiver pushes the cup receiver downwardly toward the underlying top wall of the cup-receiver platform until downwardly extending elastic anchors included in the push-and-snap lock and coupled to the underside of the floor of the cup receiver snap into engagement with an underside of the top wall of the cup-receiver platform to trap the cup-receiver platform between the floor of the cup receiver and laterally extending anchor tabs included in the downwardly extending elastic anchors so that the cupholder is retained in a stationary position on the cupholder support that is mounted on a side bolster of the seat bottom.

Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
